前言：笔者使用的gpu是gtx1070
一句话概括，cuda以及cudnn的版本不对应
踩坑过程：在官网按照其推荐配置，下载了cuda10.1以及cudnn7.6.0.64，使用anaconda安装python3.6，pip安装tensorflow-gpu1.13.1。结果出现无法找到dll的报错。具体如下：
Traceback (most recent call last):

解决过程：
1、 重复卸载安装tensorflow-gpu 失败
2、 在不改变cuda版本以及cudnn版本的前提下，安装不同版本的tensorflow-gpu，包括（1.8.0，1.9.0，1.10.0，1.12.0，1.7.0），在版本低于1.10的时候，会出现无法匹配cuda或者无法找到cuda的情况，原因可能是低版本的tensorflow-gpu仅支持cuda9.0以下版本
3、 装回cuda10.0+cudnn7.5.0.56+tensorflow-gpu1.13.1，情况依旧没有改变
4、 装回cuda10.0+cudnn7.4.2.24+ tensorflow-gpu1.13.1，情况完美解决
总结：问题应该还是出在cuda和cudnn的版本匹配问题上。
